I would suppose "fenv.h" exists in this state for uniformity purposes;
so that things would not fail because it was missing. What is needed
for the excluded architectures to not be excluded anymore?
In the specific case of "ffmpeg2", I'll need to look at its configure
process and see if it's a case of "fenv.h exists, so assume the support
it implies". Perhaps if it were missing, it would cope with that?
